More Arrests Have Been Made In Connection With Online Drug Market Silk Road, And Authorities Say More Are Coming

Stringer/ReutersRoss William Ulbricht, known online as Dread Pirate Roberts, is shown in this courtroom sketch appearing before Federal Judge Joseph Spero in U.S. Federal Court in San Francisco, California October 4, 2013.

In Seattle, the FBI arrested 40-year-old Steven Lloyd Sadler of Seattle, who operated on Silk Road under the username "Nod" and was an alleged Silk Road darling, dealing cocaine, meth, and heroin, according to Brian Krebs. Sadler's arrest followed the arrest of one of his customers in Alaska.

One of the reasons Silk Road was able to stay under wraps for so long was due to its use of Bitcoin, an online currency that is dependent from any regulated currency. It was also only accessible using a special Web browser called TOR, which was supposed to let users anonymously surf the Internet.

The FBI has already seized about 26,000 Bitcoins belonging to Silk Road customers and is still searching for over 600,000 Bitcoins, worth $80 million, that Ulbricht himself is believed to have amassed while running the site, according to The Guardian.
